Abstract

A conveyor having a conveyor belt (10), preferably of flexible steel mesh, constrained to conform to a helical conveyor path in which the tiers (11) of the helical path are arranged one above the other with a minimum vertical spacing appropriate to the product to be conveyed, wherein the tiers on the outside of the helix are supported by a fixed helical guide (22) and on the inside of the helix the tiers are self-supporting, one tier being supported by the tier underneath by an arrangement of upstanding spacer plates (20) mounted to articulated links (14) which define or support the inner longidutinal edge of the conveyor belt.
